wifi: iwlwifi: mvm: don't read past the mfuart notifcation
Published Jul 12, 2024

HIGHCVSS 3.1
EPSS 0.40%
Description
In case the firmware sends a notification that claims it has more data than it has, we will read past that was allocated for the notification. Remove the print of the buffer, we won't see it by default. If needed, we can see the content with tracing.
This was reported by KFENCE.
